I was in my best run yet. Previous record was 17.000.000 points. This time I managed to get up to 170.000.000. Then during a portal event, I shot the charged ball towards the portal next to the ball-lock imp. It ended the event, but for some reason the ball was stuck behind the imp. I tilted the table like a madman, but it wouldn't budge, then after a while the ball reset and autofired while I was still tilting. Unfortunately for me, the tilting function had built up a buffer or something, and my flippers were stuck, so my last ball fell into its doom.
I don't know if this is a bug related to the portal event, but having played Portal a lot, I assumed it might have something to do with it.
Still, I broke my previous record by 153.000.000 points. I ain't even mad!
